Further, the concave front top and rear top of said concave plasticpanel each has one perforation for up and down, a downward protrusion ofpot bottom shape is disposed below the perforation of the concaveplastic panel, a connecting bolt of the top of said universal wheelpasses through the perforation, a nut coordinated with said connectingbolt screws the bolt.

Further, a counterbore is disposed on the upper portion of saidperforation, said nut falls into the counterbore after screwing.

Further, the feet-swinging-type roller skate of concave plastic panelfuther comprising a cover, said cover places on said counterbore.

Further, said cover is a plastic cover.

Further, said concave plastic panel is injection molded.

Further, the concave front top and rear top of said concave plasticpanel tilt slightly toward the front down.

Further, said concave plastic panel is an injection piece that the sidethereof is concave shape and the overlook shape of the panel surface isolive shape, longitudinal and transverse reinforcing ribs aredistributed on the whole bottom of said concave plastic panel.

Further, a bearing is inlaid into the top of the wheel fork of saiduniversal wheel, one bolt is cup jointed inside the bearing bore, a PUwheel is connected to the wheel fork, one said universal wheel isconnected with the perforation carrying a counterbore of the concavefront top of said concave plastic panel via a nut, one said universalwheel is connected with the perforation carrying a counterbore of theconcave rear top of said concave plastic panel via a nut, two saiduniversal wheels form the same forward tilt angle with said concaveplastic panel after connecting.

Further, said plastic cover is a plastic cover of dome shape, one saidplastic cover is inlaid in the counterbore of the concave front top ofthe said concave plastic panel, the other one said plastic cover isinlaid in the counterbore of the concave rear top of said concaveplastic panel.

The beneficial effects of the present invention are: the side of theconcave plastic panel of the feet-swinging-type roller skate of concaveplastic panel is a concave shape design, the overlook shape of the panelsurface of the concave plastic panel is olive shape, such that theappearance of the feet-swinging-type roller skate of concave plasticpanel is unique and beautiful and has modern feeling, and the productionprocess is simple. The foothold of the feet-swinging-type roller skateof concave plastic panel is low off the ground, therefore which safetyis good, which is easy to learn, and which has very strong interestingwhen playing.
